That used to be advertised in the TENNIS MAGAZINE. Check the older issues if you have them. I'll check mine if I remember and get you a number.

There's another manufacter that has a mini machine. It's made in Korea, and I can't recall what it's called. They have a website that i went to a while back. The base clamps to a table and you mount the racquet on it. Then the electric tensioner is a small 4"x4"x6" box. You prestring the racquet and place this box next to the frame in front of the hole where the string is. There's a small gripper on top of the box that pulls the string, then you clamp with a flying clamp.

I had a friend (top junior in aussieland) that used to use this to string her Babolat PD's at i beleive it was 70lbs. Anyhow, she told me she hasn't broken a stick yet.

Anyone know where I can buy one of these? I was just reading on String forums and this one looks really interesting.
I have a Bartom stringer from argentina, its pretty portable, it sort of fits into a box...but this looks like it might be a bit more portable...thanks in advance!
